Your off-net bandwidth is going toincrease, unless you put some relays in. As a friend of mine just saidto me: "Welcome to your v6-enabled transit network, whether you like it or not ;-)".So you're saying Slashdot *lies*? http://tech.slashdot.org/article.pl?sid=08/08/18/226228&from=rss
They don't intentionally lie, but the study they are reporting on is uninformed.
For example:"Our research looked at all IPv6 traffic—both native and tunneled, including Teredo, which encapsulates IPv4 traffic in UDP datagrams using UDP port 3544. We found a peak of only 12 Mbps of Teredo traffic, representing around 10 percent of the
I P protocol 41 traffic."Teredo uses 3544/UDP to for Client<->Server communication. That is for relay discovery when needed, and the qualification procedure - not much traffic. Client<->Relay communication MAY use 3544/UDP, Client<- >Client communication MAY use 3544/UDP.
In my experience (packets I have been analysing in the last 24 hours for example) suggests that not many actual data packets are on UDP/3544.
I'll get some exact numbers on that in a few hours if you like.Also that report only includes data up until July 2008. uTorrent with Teredo and IPv6 stuff was released 9 August - which is the intention for my original message.
